Correct Answer: B

Rationale: The correct answer is B: bilirubin level. Jaundice, characterized by scleral jaundice, is caused by the elevation of bilirubin levels associated with red blood cell hemolysis. Checking the bilirubin level in the laboratory results will help assess the severity of jaundice in the patient. Choices A, C, and D are incorrect because the Schilling test is used to assess vitamin B12 absorption, gastric analysis is used to evaluate gastric function, and stool occult blood is used to detect hidden blood in the stool, which are not directly related to evaluating jaundice in a patient with hemolytic anemia.

Correct Answer: B

Rationale: The correct answer is B. Difficulty in arousing the patient may indicate a cerebral hemorrhage, which is life-threatening and requires immediate action. While a low platelet count (choice A) is concerning in thrombocytopenia, it does not require immediate communication unless accompanied by active bleeding or other critical symptoms. Purpura on the oral mucosa (choice C) and large bruises on the patient's back (choice D) are important findings in thrombocytopenia but do not indicate an immediate life-threatening situation like a possible cerebral hemorrhage.

Correct Answer: A

Rationale: The correct answer is A. Platelet transfusions are not usually indicated until the platelet count is below 10,000 to 20,000/µL unless the patient is actively bleeding. In this case, with a platelet count of 42,000/µL, the count is not critically low, and the patient is not actively bleeding. Therefore, the nurse should consult with the healthcare provider before giving the transfusion. Choices B, C, and D are incorrect because the presence of petechiae, low blood pressure, and oozing from the venipuncture site are common findings in patients with ITP and do not necessarily require immediate consultation before administering a platelet transfusion.

Correct Answer: C

Rationale: The patient¢â‚¬â„¢s clinical manifestations are consistent with a febrile, nonhemolytic transfusion reaction. The transfusion should be stopped and antipyretics administered for the fever as ordered.

Correct Answer: A

Rationale: The correct answer is A. A low percentage of monocytes can indicate a viral infection. This is crucial information to communicate as it suggests a specific type of infection that may require targeted treatment. Choices B, C, and D do not directly relate to an infectious process and are within normal ranges, so they are not as urgent to communicate to the healthcare provider in this context.
